John is a top notch Porsche specialist! John was able to accommodate an emergency fix on my flywheel pulley, even coming in on his day off to let me pick up the car. He recently rebuilt my 915 transmission - sending pictures and videos of the progress. He makes thoughtful suggestions on potential upgrades/repairs (not unnecessary items).

I would recommend Holleran's to anyone with an Air Cooled Porsche... read full review
